Use this dialog tab to modify the rules on which automatic trapping is
based.
When linework color areas are trapped to each other, this is done without
modifying color separations defining outlines. Basically it is assumed
that the outline is defined by the darkest separation of the darker color
area. Therefore the darkest separation of this area remains unchanged,
while the other separations are choked, i.e., the color area is slightly
overlapped by the lighter color separations of the area which does not
define the outline.
This mechanism is controlled by the parameters explained below.
Having modified these parameters, you must store them as a trapping
profile using the SAVE AS button. You cannot use any unsaved parameters.
The profile is then available on the TRAPPING/SOFT EDGES tab. It will
also include the parameters defined on the EXCEPTIONS tab. See also
page 3-55 and page 3-60.
Note:
Modifying the default trap rules may sometimes produce unwanted results.
Therefore check any changes very thoroughly before using them
in production.
